Tools

Functions exposed to the LLM to take actions

NameDescription
musicbrainz_lookupA

Fetch a single MusicBrainz entity (artist, release, recording, release-group, label, work, area, place, event, instrument, series, genre, url) by its MBID. Use inc to pull linked sub-entities and relationships, e.g. inc: ["releases","release-groups"] on an artist, or ["recordings","labels"] on a release, or ["artist-credits","url-rels"] on most entities. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_searchA

Search a MusicBrainz entity type with a Lucene query and get back ranked matches with their MBIDs. Plain text matches the entity name; fielded Lucene also works, e.g. artist:"Miles Davis" AND country:US, release:"Kind of Blue" AND format:Vinyl, or recording:"So What" AND dur:[540000 TO 560000]. Feed a returned MBID into musicbrainz_lookup for full detail. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_browseA

List all entities of one type directly linked to a given entity — e.g. every release by an artist (entity: "release", linkedBy: "artist", mbid: ), recordings on a release, releases in a collection, or events at a place. This is the complete, paged set for a relationship (unlike search, which ranks fuzzy matches). Use inc for extra detail and limit/offset to page (max 100/page). Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_cover_artA

Fetch Cover Art Archive image metadata for a release or release-group MBID — front/back cover URLs, thumbnails, and image types. Returns the image URLs (you can open or download them); it does not embed the bytes. Errors clearly when no art exists for the MBID. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_resolveA

Turn a musicbrainz.org URL (e.g. https://musicbrainz.org/artist/ or /release-group/) into the underlying entity by extracting its type + MBID and looking it up. Handy when a user pastes a MusicBrainz link. Pass inc to include linked sub-entities. Read-only. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_healthcheckA

Confirm the MusicBrainz API is reachable (and our User-Agent accepted) by looking up a stable entity, and report whether the OAuth write path is configured. Reports {ok, reachable, oauth_configured} with a plain-English hint. Read-only.

musicbrainz_submit_tagsA

Apply user tags to a MusicBrainz entity on YOUR account (needs OAuth: MUSICBRAINZ_OAUTH_* with the tag scope). Default vote: upvote adds the tags; downvote opposes them; withdraw removes your vote. Without confirm: true it returns a dry-run preview (the exact XML) and makes NO network call; with confirm: true it submits. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_submit_ratingA

Set YOUR rating for a MusicBrainz entity (needs OAuth: MUSICBRAINZ_OAUTH_* with the rating scope). Rating is 0–100 (MusicBrainz shows it as 1–5 stars in steps of 20; 0 removes your rating). Without confirm: true it returns a dry-run preview and makes NO network call; with confirm: true it submits. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

musicbrainz_modify_collectionA

Add or remove entities (releases, artists, recordings, release-groups, works, labels, places, areas, events) in one of YOUR MusicBrainz collections (needs OAuth: MUSICBRAINZ_OAUTH_* with the collection scope). Get the collection MBID from its URL (musicbrainz.org/collection/). Without confirm: true it returns a dry-run preview and makes NO network call; with confirm: true it applies the change. Data from MusicBrainz (https://musicbrainz.org), the open music encyclopedia.

TDQS

A4.4/5.0

Scored across 9 tools

Disambiguation5/5

Each tool has a clearly distinct purpose: search, lookup, browse, resolve, cover art, healthcheck, and three different write operations (tags, rating, collection). Search vs browse are explicitly differentiated as fuzzy ranked vs exact linked entities, so there is no real ambiguity.

Naming Consistency5/5

All tools follow a consistent 'musicbrainz_' prefix with snake_case operation names (lookup, search, browse, resolve, submit_tags, etc.). The pattern is predictable and uniform across the set.

Tool Count5/5

Nine tools is well-scoped for a MusicBrainz MCP server, covering the core read operations, healthcheck, and the most common authenticated write actions without unnecessary bloat.

Completeness4/5

The server covers lookup, search, browse, cover art, and user-contributed tags/ratings/collection modifications, which is strong for its domain. A minor gap is the lack of an endpoint to list a user's own collections to obtain their MBIDs, but this can be worked around from a collection URL.
